Sources - Lions starting DT Alim McNeill has torn ACL - ESPN

Detroit Lions starting defensive tackle Alim McNeill suffered a torn ACL in Sunday's 48-42 loss to the Buffalo Bills, ending his season, sources told ESPN's Adam Schefter on Monday.

In addition, starting cornerback Carlton Davis III suffered a fractured jaw in the loss, sources told Schefter. Davis will undergo surgery and be sidelined indefinitely, the sources said.

Lions coach Dan Campbell had said Sunday that he both McNeill and Davis would likely miss the rest of the season. The Lions also lost cornerback Khalil Dorsey to a season-ending ankle injury in Sunday's game, Campbell said.

The injuries are the latest setbacks to a Lions defense that had 13 defensive players on the injured reserve list entering Sunday's game. That includes star defensive end Aidan Hutchinson, who suffered a fractured tibia and fibula in Week 6.

McNeill signed a four-year, $97 million extension earlier this season and had helped stabilize Detroit's defensive line after Hutchinson's injury. He finishes the season with 25 tackles and 3.5 sacks.

Davis, acquired in an offseason trade with the Tampa Bay Buccaneers, has two interceptions, 11 passes defensed and 56 tackles this season. He will be an unrestricted free agent after the season.

The loss to the Bills snapped the Lions' 11-game winning streak. The Lions (12-2) still are in the top spot in the NFC playoff bracket, holding the tiebreaker over the Philadelphia Eagles (12-2) based on winning percentage in conference games, with three games to go.
